The problem with Chatroulette and other video based communication is the fact that people can see you. This means that I would have to shower, shave and wear something nice before going online. As it takes me at least four hours just to do my hair, this is simply not practical. I generally write in track suit pants and t-shirt while eating pizza, which would be unfair to the other parties to have to view.
Having heard a lot about Chatroulette, I decided to have a look. For every ten video connections, eight of them were fat people playing with their penis. Apart from a couple of interesting people I met, it was possibly the most pointless website I have ever been on. Just don't even bother.
